Red Hat Bugzilla – Bug 455509
iwl3945 cannot be renabled from linux after power failure
Last modified: 2008-11-28 06:29:20 EST
Description of problem:
Wireless hardware on Acer 5920 laptop (iwl3945) gets switched off when the
wireless key is pressed, or the laptop dies due to a flat battery. When this
happens it is impossible to re-enable the wireless from Linux. My only choice is
to reboot to Vista, which I fortunately decided to dual boot rather than go pure

This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
This bug is no longer applicable to Fedora 10. Using fedora 10 live CD wireless can be switch back on (by turning of wireless in network manager, then re-enabling).
Still not ideal, it should be switch on during boot if the network manager has it as enabled. I will raise a new bug to cover that on Fedora 10.
